help with name checking script

[Kevin Darcy]

Try the "host" utility (in the contrib directory of the BIND distribution).
Not only is its output format simpler to parse than "dig"'s or
"nslookup"'s, but it appears to have a more meaningful exit code (from the
few tests I ran). Seems like it might be a better fit for what you're
trying to do.
